INGOT-MOLD.
Specification of Letters Patent.
Patented May filth 19211..
Application filed September 17, 1920. Serial No. 410,983.
To all whomit may concern:
Be it known that I, OnvILLE ALDEN F0 illustrated in the accompanying drawings,
that form part of the same.
The invention consists essentially in the novel means employed, whereby the bottom of the mold is readily removed and replaced, and the receptacle so arranged as to avoid fins in the ingot.
The objects of the invention are to facilitate the production of ingots in the manufacture of articles peculiar to the steel industry; to economize in respect to the parts of the molds; to insure regularity in the casting produced; and generally to provide a reliable, durable and convement mold.
In the drawings, Figure 1 is a sectional perspective view of the mold.
Fig. 2 is a perspective detail of the removable bottom.
Fig. 3 is a mid-sectional view through the bottom.
Fig. 4 is a vertical sectional view. of the sand top.
Like numerals of reference indicate corresponding parts in each figure.
Referring to the drawings, the casing 1 is of tubular formation having the tapered inner wall 2 and the three leg extensions 3 below the cylindrical lower annular recess 4, forming the seat 5 for the removable bottom 5.
The removable bottom 5 is annularly grooved at 6 and is faced on both sides so as to be reversible, and this bottom can be machined down until it is too light to use.
The stepped kee er 7'is in late form having the central ho e 8 and t e plain face 9 engaging the bottom 5 and the ste s 10, 11 and 12 with inclined surfaces, w ich are engaged respectively by the pins 13, through the pin holes 14 or 15 in the legs 3, thus there are three or more sets of steps and three or more steps in each set to aceommo date diderent thicknesses of bottom.
In regard to the sand top 16, this is made of awall in substantially conical form having in the base the annular groove 17 which is filled with fire clay 18 to receive the proectmg upper end 19 of the inner wall 2, thus forming a tight joint and avoiding fins ofepy consequence in the casting at that pom The operation of casting with these molds may be readily understood from the description of the details, as the bottom is fixed by the pins according to its thickness and of course, the particular steps used and the metal poured into the sand top and casing. The removal of the bottom can easily be done after the pins are taken out by drop ping said bottom and inserting the hand and grasping the bottom in the groove.
Various changes may be made in the details of the construction without departing from the spirit of the invention, and so long as such changes are within the claims for novelty following, the protection accorded shall not be invalidated.
What I claim is 2- I 1. In an ingot mold, a casing having an annular recess at the lower end forming a bottom seat, a bottom fitting to said seat and a keeper plate stepped for various thicknesses of the bottom and held by pins.
2. In an ingot mold, a casing having an annular recess forming a bottom seat and leg extensions below said recess and pin holes in said legs, a bottom fitting to said seat, a stepped plate forming a keeper for said bottom, and pins through said legs engaging said steps.
3. In an ingot mold, a casin having an annular recess below the meta receptacle, forming a bottom seat and leg extensions below said recess, a bottom having finished faces and an annular groove in the side wall,
a keeper plate having inclined surfaces and pins through said legs engaging said inclined surfaces.
Signed at the city of Montreal, in the Province of Quebec, in the Dominion of Canada, this 8th day of September 1920.
